Subject: [FFmpeg-devel] [PATCH v4 12/16] vulkan: add ff_vk_exec_add_dep_wait_sem()
Date: Thu, 13 Mar 2025 18:03:44 +0100
Message-ID: <20250313170355.92290-13-dev@lynne.ee> (raw)
In-Reply-To: <20250313170355.92290-1-dev@lynne.ee>

This adds a function which adds a regular timeline semaphore
as a wait-only dependency.
